Abstract:
A decorator assembly (10) is provided. The decorator assembly (10) includes a mandrel turret assembly (20). The mandrel turret assembly (20) includes a rotatable turret (24), a number of mandrels (26), and a number of independent ink stations (100). Each mandrel (26) is rotatably coupled to the turret (24). Each mandrel (26) extends generally radially from the turret (24) and are disposed generally in a plane about an axis of rotation (74). The turret (24) is structured to rotate about an axis of rotation (74) thereby moving each mandrel (26) over a generally circular path of travel. Each independent ink station (100) is disposed adjacent to the path of travel of the mandrels (26).
Abstract:
A hydrostatic/hydrodynamic fluid bearing assembly (100) for a can bodymaker (10) is provided. The hydrostatic/hydrodynamic fluid bearing assembly (100) is separate from the ram body (50). The outboard bearing assembly (60) includes a carriage assembly (62) and an outboard guide bearing assembly (60). In this configuration, the ram body (50) may form a can body (10) in a traditional manner, but fluid bearing assembly fluid is not applied to the ram body (50).
Abstract:
A can bodymaker (10) is provided. The can bodymaker (10) includes two rams (250) that travel over a generally vertical path. The bodymaker (10) includes a housing assembly (11) and an operating mechanism (14) structured to move a number of ram assemblies (250) over a vertical path of travel. The operating mechanism (14) includes a crankshaft (150), a motor (152), a link assembly (180), and a number of ram assemblies (250).
Abstract:
A cooling gas system for a can bodymaker tool pack is provided. The cooling gas system uses a compressed gas to cool a punch and/or a die pack. That is, a compressed gas is delivered to at least one location adjacent the punch and die pack. A nozzle assembly directs the compressed gas toward a selected location. As the compressed gas passes through the nozzle assembly, or immediately after passing through the nozzle assembly, the compressed gas expands. As is known, an expanding gas cools as it expands. Thus, a cool gas is directed to the surface of the punch and the die pack. The cool gas absorbs heat from the punch and die pack thereby cooling the heated components.
Abstract:
A spray assembly includes a power source, a motion control mechanism such as a cam box, and at least one spray head structured to apply a coating to a plurality of can ends. Each spray head includes a mounting member, a pivot member, a gun assembly including a plurality of spray guns, and a transfer mechanism for transferring a predetermined motion induced by the cam box from the cam box to the pivot member. Each of the spray guns applies the coating to the can ends in accordance with the predetermined motion. Preferably the predetermined motion as an oscillating motion transferred to the pivot member by belts, thereby oscillating the spray guns. The spray assembly may include a plurality of spray heads, wherein can ends of the same or different sizes are transferred in lanes to a corresponding one of the spray heads.
Abstract:
Apparatus for forming container shells (5) from material fed into a press (1), including, at a single station, tooling for curling the shell (5) and tooling for forming or reforming the shell (5) including a punch assembly (20) and a die assembly (100) carried by the press (1) adapted to curl and form or reform the shell (5) in a single stroke.
Abstract:
A printing plate pressure adjustment system for a can decorator including a printing plate cylinder assembly having a printing plate cylinder drive shaft, and a blanket wheel. The system includes an actuator, a control system structured to control operation of the actuator to adjust a pressure between the printing plate cylinder assembly and the blanket wheel, an eccentric bushing disposed around the printing plate cylinder drive shaft, wherein rotation of the eccentric bushing causes the printing plate cylinder to move toward or away from the blanket wheel, and a drive mechanism coupled between the actuator and the eccentric bushing, wherein operation of the actuator causes the drive mechanism to rotate the eccentric bushing.
Abstract:
A drive assembly for a necker machine having a frame assembly and a plurality of processing stations includes: a plurality of drive sub-modules. Each drive sub-module includes: a primary input shaft, a first primary output shaft operatively coupled to the primary input shaft, and a second primary output shaft operatively coupled to the primary input shaft. For a first drive sub-module: the primary input shaft is operatively coupled to, and driven by, a main drive assembly motor, and the first primary output shaft is operatively coupled to, and drives, an associated first drive shaft of a first processing station. For a second drive sub-module: the primary input shaft is operatively coupled to, and driven by, the second primary output shaft of the first drive sub-module, and the first primary output shaft is operatively coupled to, and drives, an associated first drive shaft of a second processing station.
Abstract:
A ram drive assembly for a can bodymaker includes a mounting assembly and a number of forming assemblies supported thereon, each including: a stationary assembly, having a die pack and a domer, and a moving assembly having a ram assembly and a cam follower assembly. The die pack defines a passage having a proximal and a distal end, with the domer disposed adjacent the distal end. The ram assembly includes a ram body having a proximal and a distal end, with the cam follower assembly coupled to the proximal end. The ram body is structured to reciprocate through the passage between a retracted and an extended position. The ram drive assembly includes: a cam having a body with a number of surfaces for engaging each cam follower assembly; and a motor having a rotating output shaft operatively coupled to the cam body for rotating the cam body.
Abstract:
A redraw assembly is for a bodymaker having a ram, a die pack, and a drive mechanism. The redraw assembly includes a carriage assembly, a ram guidance system, a hold down assembly, and a cam follower hold down frame.
